*Mfr- IMPROVEMENT IN sTovEs.

The Schedule referred to in these Letters Patent and making part of the same.

To all z cltom it may concern.:

Be it known that'I, LYMAN GL'nAsoN, of Milford, in the county of Worcester and State of Massachusetts, have invented an Improvement in Stoves; and I do hereby declare that the following, taken in connection with the drawing vwhich accompanies and forms part ot' this specification, is a description of my invention snfiieient to enable those skilled in the art to practice it.

My invention relates to the-construction of fire-pot linings for stoves, furnaces, 85e., with reference to a provision for freeing the bottom' of a tire from clinker andashes, wit-hout destroying or impairing the lire fire or coals in the upper part ofthe lire-pot. v

M yinvention consists, primarily, in the employment, in the .lower part of 'the rcfpot, of 'a lining made np of lire-bricks,'the face'of eaclrofwhich hasfa swell between the top and bottom, Tand in forming each one of these swelled bricks with vone'or more vertical liutes o1'.recesses,or depressions, -made in-its front face.

'The drawing represents a portion-of a stove or 'stovebody, embodying my improvement.

A shows the tire-pot in sectional elevation, the section being taken on the line y g`/. v i

B is a cross-section, on the line :c x.

O shows one ofthe swelledre-pot bricks.`

c denotes the stove-body or cylinder.

c, the lire-pot or chamber. l

ll e f, three courses of lining to-the,-tirepot, such lining being preferably made ot're-bricks.

'lhe two courses l e may be made of common re- I Witnesses:

bricks, but, in the lower course, j, the bricks are made of peculiar shape, as followsz` f .c

Each brick f, at its top andbottom, of substantially the same thickness as thev bricks d e,lbut theA faeeof each brick swells inwardly, as seen at g, so

that, vwhen the fire-pot is charged, and the coal at the bottom is somewhat consumed, the h 'ody of c oal'in the tire-pot will vbe sustained by the contracting portion of the lire-pot within the lower? 'course of bricks, and above the line x a', to such extent as to permit the e grate to `be turned into vert-ieahpositionwithoutdisturbance thereof, letting down the asheslcinders, and clinkers which arein the bottom of the-'lirepot,'below the line .mythe enlargement of thefre-pot', (below' this line,) produced bythe swelling formationof the bricks f, causing the ashes, cinders, audclinker to fall freely into the ash-pit as soon asthevgrateis turned into such vertical position. YWhen the grate is turnedback into horizontal position, and is'slightlyshaken,

the/,lire coals above fall down to the grate without injury to the lire. By this construction a stove may be kept free from ashes and clinker without, at any time, lett-ing the vlire go out. Y

Torfacilitate the freeing` ot' the fire-pot from ashes,

I prefer to make each brick f'with a depression vor,

fa vertical groove or depression extending along such face, substantially as described.
